Capwap Mailing List: Re: Issue 217

[Margaret Wasserman (margaret]

Hi Abhijit,

I'm sorry for not mentioning Sudhanshu's correction in the previous  
message.  This is a necessary correction, as Pat has already indicated.

I view this as a helpful amendment to the text that Pat circulated,  
and not as an objection to the proposed changes.

Thanks to you, and especially to Sudhanshu for noticing this!

Margaret
